'1l-hef:presentvv invention relates to newand useimprovements in. saw sets' of' a, type as covered. in; my prior U.. S.. Letters Patent No. $141,695', dated. lllecernberZlv, 1938'.V

An importantv object of the present invention is toprovide a saw set of: the` aforementioned character in which a tooth-setting jaw is provided having anA elongatedI head adapted to con"- tact the beveled side; of. the tooth. for' exerting pressurey thereon during the saw setting` action., the head of the.` saw setting jaw being adapted fon use with fine. or' coarse. saw teeth and em.- bodying means: for adjusting the.: head of; the setting jaw in` accordance witlrtha character of the tooth being set.-

A further object of the present invention is to provide a springeactuated Wedge adapted to grip the side of the saw for holding the same rmly while the teeth are being set.

A further objectl of the invention is to provide a device of this character of simple and practical construction, which is eiiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer tolike Darts throughout, and in which:

Figure 1 is a side elevational view of the saw set with parts shown in section and illustrating the tooth-setting head in use.

Figure 2 is an edge `elevational View thereof.

Figure 3 is a vertical sectional view taken substantially on a line 3 3 of Figure 1.

Figure 4 is a transverse sectional View taken substantially on a line 4`4 of Figure 1.

Figure 5 is a vertical sectional view taken substantially on a line 5-5 of Figure 1, and illustrating the anvil-carrying section.

Referring now to the drawing in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral I designates the jaw-carrying section, while the numeral 2 designates the anvil-carrying section,

The section I vis relatively longer than the section 2, the section I tapering toward its upper r end, as indicated at 3, and terminates in a at surface to provide a striking head 4 to receive a hammer blow by a suitable tool.

The section I is provided with a shoulder 5 at the junction of the tapered portion thereof with s claims. (o1. vrt-"zzo" the section 2 and the section-2 has a ilat upper end disposed in abutting relation with the shoulder 5, aswell as a fiat inner face 6 for disposal in'face-to-face Contact with the ilat inner tace I of the section I.

The sections3 I1 and 2 are detachably secured to each otherby: a bolt `8` which extends through the section I and is threaded in the section 2..v

The lower" portions of each of the sections," are reduced. and provided with flat confronting-faces disposed in spaced-apart' relationwith respect to each other for receiving asawblade 9' between the' same and the opposed face of. the section I has ar recess I-Ilf formed therein and in whichl is slidably mounted a wedge block. Ict yieldably urged; downwardly toward. the lower end. of.Y the section. I` by a coil spring I-2 toset.- up frictional wedging action against the saw blade.

The inner portion of the spaced confronting faces of the sections are formed with registering -recesses I3 and I4, respectively, the recess I3 having a setting jaw I 5 mounted therein of elongated construction and formed with beveled upper and lower edges I6 and I'I, the beveling I6 being relatively wider than the beveling I7, as will be apparent from an inspection of Figure 1 of the drawing.

The jaw I5 is formed on a square shank I8 slidably mounted in a complementary shaped passage I9 in the section I and projecting from the shank I8 is a screw 20 on which a nut 2I is threaded and retained in a chamber 22 in the section I with the edges of the nut projecting outwardly at opposite sides of the section I, as indicated in Figure 2 of the drawing, to provide finger-gripping means for the nut to adjust the head I5 into and out of contacting engagement with one side of the teeth 23 of the saw 9.

Positioned in the recess I4 is an anvil 24 like- Wise of elongated construction formed on its square-shaped shank 25 from which a screw 26 projects for manipulation by a nut 2'I carried in the section 2 similar to the nut 2l of the section I and adapted upon manipulation of the nut 2l to move the anvil toward and away from the head I5.

As illustrated in Figure 3 of the drawing, one side ofthe wedge I I is provided with a laterally extending pin 28 projecting outwardly of the .section I through an opening 29 for releasing the wedge from the saw, when desired.

In the operation of the device, the saw blade '9 is positioned between the spaced-apart confronting faces of the lower ends of the sections t I and 2 and the wedge II is moved downwardly by the pin 28 to cause friction gripping engagement thereof with the saw.

The teeth 23 of the saw are disposed between the head I5 and handle 24 so that upon striking a hammer blow upon the striking head 4, the beveled edge of the setting jaw I5 will bend the teeth of the saw against the anvil at the desired angle.

Either of the beveled edges I6 or l1v may be brought into contacting engagement with the teeth of the saw in accordance with the size of the teeth being set.

It is thought from the foregoing description that the advantages and manner of operation of the device will be readily apparent to those skilled in the art.

It is to be understood that' changes'- may be made in the construction and in the arrangement of the several parts as herein described and i1'- lustrated in the accompanying drawing, provided that such changes fall within the scope of the appended claims;

Having thus described the invention, what I claim is:

1. A saw set comprising a body havingspaced inner faces'to receive av saw blade between the same, and avsaw tooth-receivingv chamber atthe inner ends of the faces, a tooth-engaging jaw positioned atv one sidel ofi saidy chamber, saidI jaw being of elongated constructiony withzits` opposite ends beveled forl selective engagement with the tooth of the saw, an anvil-positioned in the chamber atthe oppositesideof the tooth, independent means for adjusting the jaw and the anvil relative to each other, said body having a striking head adapted for receivingl ahammer' blow at one end thereof, a wedge slidably mounted in the body, spring means engaging the wedge to urge the latter into friction gripping engagement with the saw, said body having an opening therein adjacent the wedge, and a pin carried by the wedge and projecting outwardly of the body through said opening and providing finger gripping means for releasing the wedge for engagement with the saw.

2. In a saw set, a body comprising spaced inner faces to receive a saw blade therebetween and a saw tooth receiving chamber at the inner ends of said faces, a tooth engaging jaw embodying an elongated head mounted for lateral movement within said chamber, an anvil mounted for lateral movement within said chamber and cooperating with said jaw, means for adjustably moving said jaw toward and from said anvil, and means for adjustably moving said anvil toward and from said jaw.

3. In a saw set, a body comprising spaced inner faces to receive a saw blade therebetween and a saw tooth receiving chamber at the inner ends ofthe faces, a tooth engaging jaw embodying an elongated head'mountedifor lateral movement within said chamber, an anvil mounted for lateral movement within said chamber and cooperating with said jawmeans for adjustably moving said jaw toward and from said anvil, means for adjustably moving said anvil toward and from said jaw, one of said faces being provided wth an elongated recess adjacent its lower end thereof, and a wedge yieldably and slidably mounted within said recess adapted for frictional gripping engagement with the. saw when positioned within said faces to secure the latter against movement.
